### March 11 , 2009 .

heello !

Well
today we didn't really do anything but TLE .
Oh and , for the people who haven't done TLE yet , the subject we had to do is
Rates and Ratio's .

Since I forgot
to do yesterday's blog , I'm going to talk about yesterday's math . Yesterday , the number of the day was 7835.621 .

Mr.Isfeld told us to work on our text book work , page 198 questions 2 - 14 .
Probability tree's and tables .

For example , if you were to flip a coin and roll a die , what are the possible outcomes
that the coin will land on
heads and the die to roll a 4 ?
First , you would have to make a Tree Diagram for the die .

It might look like this :

A probability tree diagram shows all the possible events.
The first event is represented by a dot.
From the dot, branches are drawn to represent all possible outcomes of the event.
The probability of each outcome is written on its branch
.

Then , for the coin , you need to draw a Table Diagram .
Which would look something like :

Sample space:
{ H1, H2, H3, H4, H5, H6,
T1, T2, T3, T4, T5, T6 }

The probability of each of these outcomes is 1/2 • 1/6 = 1/12

And to end this off , I am going to ask a probability question ,

An ice chest contains 9 cans of apple juice , 8 cans of grape juice , 7 cans of orange juice , and 5 cans of pineapple juice . If you reach into the container and randomly select 3 cans from the chest , what's the probability of selecting no grape juice ?

For the next post , I choose .. DARNELL .
